EcoFlow DELTA 3 Plus Portable Power Station | 1,024Wh, 1,800W

EcoFlow DELTA 3 Plus: fast charging home backup that grows to 5kWh

The EcoFlow DELTA 3 Plus is the power station reviewers keep recommending to people who want one unit that simply works. It stores 1,024Wh in a LiFePO4 battery, runs 1,800W of appliances with a 3,600W surge, and refills from a wall outlet in 56 minutes. When one kilowatt hour stops being enough, it expands up to 5kWh with EcoFlow extra batteries, including batteries from the older DELTA 2 range.

It is also built for home backup specifically: a switchover under 10 milliseconds for sensitive electronics, quiet enough for a bedroom, and 1,000W of solar input for when the outage lasts longer than the battery.

What the Ecoflow DELTA 3 Plus can run

Estimated runtimes on a full charge, one device at a time, assuming about 85% usable capacity after inverter losses. Add an extra battery and these figures multiply accordingly.

Running several devices at once shortens these times. Size a system around your own appliance list with our power station sizing calculator, or check what each device draws with the wattage calculator.

Key features

0 to 100% in 56 minutes

With EcoFlow’s X-Stream charging and up to 1,500W of AC input, the Ecoflow DELTA 3 Plus fills completely in 56 minutes from a normal wall outlet. Even a 30 minute charge gives you hours of backup, which is what matters when a storm warning arrives with little notice.

Expandable up to 5kWh

Connect an EcoFlow extra battery and capacity grows from 1kWh up to 5kWh. It is unusually flexible here: DELTA 3, DELTA Pro 3, DELTA 2 Max and DELTA 2 extra batteries all work, so if you already own an older EcoFlow battery, there is a good chance it carries over. Ask us before you buy and we will confirm compatibility.

1,800W output, 3,600W surge

Enough for a refrigerator, microwave, coffee maker, TV, computers and most corded power tools, with a 3,600W surge for motors and compressors starting up. X-Boost mode lets it run heating appliances rated above 1,800W, such as kettles and hair dryers, by lowering the voltage slightly.

1,000W of solar across two inputs

This is what separates the Plus from the standard DELTA 3. Two 500W MPPT inputs take up to 1,000W of solar combined, recharging the unit fully in about 70 minutes of good sun. It can also charge from a car with EcoFlow’s alternator charger, or pair with the EcoFlow Smart Generator 3000 (Dual Fuel), which starts and stops automatically to extend runtime indefinitely.

Under 10ms UPS switchover

Keep your router, desktop computer or CPAP machine plugged into the Ecoflow DELTA 3 Plus while it is connected to the wall. If the grid drops, it switches to battery in under 10 milliseconds, fast enough that sensitive equipment keeps running without a restart.

Quiet, durable and app controlled

It runs at around 30dB under 600W, quiet enough for a bedroom or nursery. The LFP battery is rated for 4,000 cycles to 80% capacity, which EcoFlow puts at about ten years of regular use, and the battery pack is IP65 protected. The EcoFlow app lets you monitor usage and schedule charging for off peak hours to save on electricity bills.

DELTA 3 Plus vs DELTA 3 and DELTA 2

The Ecoflow DELTA 3 Plus sits in a crowded family, so here is how it compares with the models people most often weigh it against.

Which one? If you will recharge from solar, or want to fast charge a laptop straight from the unit, the Ecoflow DELTA 3 Plus earns its place over the standard DELTA 3. If you only ever charge from the wall, the standard DELTA 3 gives identical runtime. Against the DELTA 2, the DELTA 3 Plus is the clear upgrade: longer battery life, faster UPS switchover, double the solar input and more room to expand.

Frequently asked questions

Can you connect two EcoFlow DELTA 3 Plus units together?

Not to combine them into one larger power station. The way to add capacity is an EcoFlow extra battery, which takes a single DELTA 3 Plus up to 5kWh through one screen and one app. Two separate units on different appliances work perfectly well.

Which extra batteries work with the Ecoflow DELTA 3 Plus?

DELTA 3, DELTA Pro 3, DELTA 2 Max and DELTA 2 extra batteries, up to 5kWh in total. That makes it a sensible upgrade for anyone who already owns an older EcoFlow battery.

Is the EcoFlow DELTA 3 Plus worth it?

For home backup, yes. The 56 minute recharge, under 10ms UPS switchover and room to grow to 5kWh cover what matters in an outage. It is worth the premium over the standard DELTA 3 mainly if you will use solar; if you only charge from the wall, the standard model gives the same runtime.

What is the difference between the Ecoflow DELTA 3 and the Ecoflow DELTA 3 Plus?

Same battery, same output and the same 56 minute wall charge. The Plus adds a second solar input for 1,000W in total, and a faster 140W USB-C port.

Can it run a refrigerator?

Yes. A full size fridge typically runs around 16 hours on a full charge because the compressor cycles on and off, and the 3,600W surge handles its startup comfortably.

Is it safe to use indoors?

Yes. There is no fuel, exhaust or carbon monoxide, so it can run in a bedroom or beside a CPAP machine. That is the key advantage over a gas generator, which FEMA advises keeping outdoors and at least 20 feet from doors and windows. Its power outage checklist is worth reading before storm season.
